Immunologic screening was used for examining children of five St. Petersburg regions (4155 subjects) and workers of two industrial enterprises (7700 subjects). Tuberculosis infection level in children living together with subjects of groups I, II, Va, Vb and VII dispensary record and tuberculin sensitivity in adults were determined. New risk groups of tuberculosis development have been suggested which include children from the families of subjects with residual changes of past respiratory tuberculosis with a high risk of its reactivation and adults having hyperergic tuberculin sensitivity. BCG revaccination postponement in adults aged 27-30 years is valid in conditions of low tuberculosis prevalence.
